  2. Delay calculation - Wikipedia

    en.wikipedia.org/wiki/Delay_calculation

    Elmore delay [5] is a simple approximation, often used where speed of calculation is important but the delay through the wire itself cannot be ignored. It uses the R and C values of the wire segments in a simple calculation. The delay of each wire segment is the R of that segment times the downstream C. Then all delays are summed from the root.

  3. Bucket-brigade device - Wikipedia

    en.wikipedia.org/wiki/Bucket-brigade_device

    A well-known integrated circuit device around 1976, the Reticon SAD-1024 [2] implemented two 512-stage analog delay lines in a 16-pin DIP. It allowed clock frequencies ranging from 1.5 kHz to more than 1.5 MHz. The SAD-512 was a single delay line version.

  4. NL5 circuit simulator - Wikipedia

    en.wikipedia.org/wiki/NL5_Circuit_Simulator

    Non-linear components are represented as piecewise-linear, or as a function (simulated with one step delay). For mixed-signal systems, system-level, and behavioral modeling NL5 uses simple basic digital, function, C-code, and DLL components. Practically all parameters of NL5 components can be set to positive, negative, zero, or infinity value.

  5. Group delay and phase delay - Wikipedia

    en.wikipedia.org/wiki/Group_delay_and_phase_delay

    The group delay and phase delay properties of a linear time-invariant (LTI) system are functions of frequency, giving the time from when a frequency component of a time varying physical quantity—for example a voltage signal—appears at the LTI system input, to the time when a copy of that same frequency component—perhaps of a different physical phenomenon—appears at the LTI system output.

  6. Static timing analysis - Wikipedia

    en.wikipedia.org/wiki/Static_timing_analysis

    Static timing analysis (STA) is a simulation method of computing the expected timing of a synchronous digital circuit without requiring a simulation of the full circuit. High-performance integrated circuits have traditionally been characterized by the clock frequency at which they operate. Measuring the ability of a circuit to operate at the ...

  7. Analog delay line - Wikipedia

    en.wikipedia.org/wiki/Analog_delay_line

    A series of resistor–capacitor circuits (RC circuits) can be cascaded to form a delay. A long transmission line can also provide a delay element. The delay time of an analog delay line may be only a few nanoseconds or several milliseconds, limited by the practical size of the physical medium used to delay the signal and the propagation speed ...

  9. Phase-locked loop - Wikipedia

    en.wikipedia.org/wiki/Phase-locked_loop

    Figure 1. Simple analog phase locked loop. A simple analog PLL is an electronic circuit consisting of a variable frequency oscillator and a phase detector in a feedback loop (Figure 1). The oscillator generates a periodic signal V o with frequency proportional to an applied voltage, hence the term voltage-controlled oscillator (VCO).
